Emulab FAQ: Testbed Operations: What are sitevars?

Site variables ("sitevars") are stored in the sitevariables database table. Each one has a name, a description (NOT OPTIONAL!), a default value, and a current value. If the current value is NULL, the default value is used.

There is a mechanism in the install process to ensure all needed site variables exist before installing.
